Definitions
- the invention relates to a single-valve propulsion process with multiple injection and multiple combustion cycles, particularly in jet engines used in the aeronautical field, and more particularly, the reactors operating according to the thermodynamic cycle of the invention. Humphrey, by constant-volume combustion of a mixture of compressed air and fuel.
- the invention also relates to a so-called thermoreactor engine operating according to this method.
- the qualifier "multiple” means "at least three”.
- the invention can also be applied to any type of internal combustion engine pulsed type thermodynamic cycle, for example motor vehicle engines, whether at constant pressure or volume in the combustion chamber.
- the main advantage of the Humphrey cycle is to use more efficiently the energy that can provide the fuel by achieving a constant volume combustion followed by a total relaxation of the burnt gases thus producing level kinetic energy Student.
- the reactor will produce power by driving a turbine or directly from the thrust.
- the reactors producing a constant volume combustion also called “thermoreactors”, then offer decisive advantages over turbomachines operating with constant pressure combustion, particularly in terms of compactness -which allows them to be housed in the wings of a aircraft - in terms of mass, thrust and thermodynamic efficiency (with consumption gains greater than 10%).
- each thermoreactor comprises at least one compressor, at least one nozzle, and a combustion chamber connected to the compressor. and to the nozzle by two sets of valves, respectively injection and ejection.
- Each combustion cycle is conventionally composed of three phases: a phase of admission or injection of a preformed mixture of compressed air and fuel, a combustion phase proper of this gas mixture by a controlled ignition, and a relaxation phase with exhaust gas ejection.
- the thermoreactors operate in parallel and each thermoreactor is out of phase so that, during the same combustion cycle, the thermoreactors cover all the phases of this cycle.
- valves are rotated by appropriate electric motors synchronously so that when a premix of fresh gas is introduced into the combustion chamber via a neck formed between two injection valves (phase d). intake), the two ejection valves close the gas outlet. Similarly, after combustion of the mixture, the injection valves close the inlet to the combustion chamber and the ejection valves form a gas outlet neck during the expansion of the flue gases (ejection phase). .
- valves have appropriate cylindrical shapes elongate or oblong outer section and are positioned so that, during their coordinated rotation, they can form successively open connection necks and closed twice per rotary cycle. In other words, each cycle of rotation of a set of valves covers two combustion cycles.
- thermoreactor is also of particular interest if it was possible to miniaturize it. Indeed, a reduction in dimensions and therefore The volume of such thermoreactors induces a reduction in their mass and their bulk. Therefore, applications in the space field are possible as well as in other areas (reduced models, new fuel experiment, etc.). However, a miniaturization rate of the order of 5 to 10 - allowing for example to change from a combustion chamber volume of a liter to 100 or 200 cm3 - decreases the power of propulsion provided by the thermoreactor, everything else equal.
- the injection speed of the valves must be substantially increased, which causes significant problems of valve stability and sealing between these valves and the combustion chamber housing, while the speed of the valves ejection of the afterburning gases - which is only a function of pressure and temperature conditions - remains substantially constant.
- the invention aims to overcome these problems by providing for the implementation of a single injection valve of particular conformation to achieve several fuel injections and combustions per cycle of rotation of these valves.
- the subject of the present invention is a single-valve propulsion process with multiple injection and multiple combustion cycles, comprising, by combustion cycle, a phase for admitting fresh gases that have been premixed at the inlet of the combustion chamber. a combustion chamber, a combustion phase proper of these gases in the body of the combustion chamber, and a flue gas expansion phase at the ejection outlet of this combustion chamber.
- at least three combustion cycles are performed per complete rotation cycle of multiple conformations able to form accesses for the admission of the fresh gas mixture into the combustion chamber for a predetermined period.
- These injection conformations succeed each other regularly with each combustion cycle by rotation around a single transverse axis.
- Each of these conformations injects substantially the same amount of premix of fresh gas into the combustion chamber, this amount being determined by the geometry and rotational speed of the conformations so that establish in the combustion chamber an optimal pressure. Such optimal pressure maximizes the performance of the turbomachine.
- a storage preferably integrated in the combustion chamber is carried out by sampling high-pressure and high-temperature burnt gases and, after the admission of new fresh gases from the following combustion cycle, the hot gases high pressure sampled from the previous combustion cycle mix with the low pressure fresh gas by reinjection into the combustion chamber caused by pressure difference and trigger the ignition of the fresh gases;
- the collection of burnt gases is carried out via the conformations during time intervals when these conformations are turned towards the interior of the combustion chamber;
- the storage is common to at least two sampling and then reinjection operations carried out simultaneously in the combustion chamber; a fuel injection is integrated into a flow of compressed air upstream of the combustion chamber to form the premix of fresh gas introduced into the combustion chamber during the intake phase of each combustion cycle, the fuel being injected into the air flow via rotating lights which periodically and channelally open into said flow in synchronization with the duration of the admission phase;
- one of the multiple ejection conformations form an access for the evacuation of the combustion chamber flue gas, ejection conformations succeeding each other regularly by rotation about at least one single transverse axis to form the evacuation accesses for the same duration as the formation of the admission ports by the injection conformations;
- a cooling of the burned gases is effected by heat exchange as close as possible to the ejection conformations
- the pre-mixing conformations of fresh gas in the combustion chamber and the flue gas evacuation conformations are synchronized so that no fuel is injected into the air flow nor any admission access to the combustion chamber is formed during the combustion phase, and in which the phases of admission and ejection of gas in the combustion chamber have a period of recovery during which the fresh gases entering the combustion chamber through the inlet ports discharge the remaining burned gases from the previous combustion cycle through the exhaust ports.

- the fuel injector is located near the injection valve so that the air-fuel premix of fresh gas is formed as close as possible to the admission ports to the combustion chamber while remaining compatible with the total vaporization time of the premix;
- At least one flue gas cooling duct in which circulates a coolant, is located closer to the ejection valve; the cooling duct (s) is (are) chosen from an upstream shield located in the combustion chamber, an internal duct to the ejection valve centered on its axis of rotation and / or a shield downstream located in the exhaust gas nozzle;
